What you are actually paying for

Find the row that matches your situation. Quotes that differ wildly from each other usually differ in scope, not in price.

ScenarioTypical cost
Tuckpointing and cap replacementMaintenance-level repair on a sound structure.$500–$1,500
Crown rebuild and flashing repairWater intrusion prevention at the top and base.$800–$2,000
Partial rebuild, top 4 feetCommon when the crown and upper courses are deteriorated.$1,500–$4,000
Stainless steel flue liner installationRequired for safe wood or gas appliance venting in an unlined chimney.$1,500–$3,500
Full chimney rebuildFrom the roofline up; foundation and lower courses may be sound.$5,000–$10,000

What moves the price

In descending order of impact. These are also the questions worth asking a contractor whose quote sits outside the range above.

  1. Scope of repair

    Tuckpointing deteriorated mortar joints is the least expensive repair. Rebuilding the upper courses, replacing the crown, or installing a liner each step up in cost.

  2. Chimney height and accessibility

    Roofline chimneys are accessible. Chimneys on steep roofs or above two stories require scaffolding or a chimney hoist.

  3. Flue liner condition

    A cracked or missing flue liner requires a stainless steel insert at $1,500 to $3,500. Unlined chimneys used for gas or wood burning are a safety hazard.

  4. Crown and cap

    A cracked chimney crown lets water into the masonry, causing freeze-thaw damage. Crown rebuild or seal costs $300 to $1,500.

  5. Flashing at the roofline

    Failed chimney flashing causes roof leaks. Step flashing and counter flashing replacement costs $300 to $800 and is often done with roof work.

Can you do it yourself?

Not a DIY job

Chimney repair at height requires scaffolding and masonry skill. Flue liner installation affects combustion safety and carbon monoxide exposure. Hire a certified chimney professional (CSIA certified).

Permits and inspection

A building permit may be required for chimney rebuilds. Liner installations are often inspected as part of a wood stove or fireplace permit.

When this cannot wait

  • Bricks or stones falling from the chimney
  • White staining (efflorescence) indicating water penetration
  • Chimney leaning or separating from the house
  • Using a fireplace with a known cracked flue liner

Common questions

How much does chimney repair cost?
Tuckpointing and minor repairs run $500 to $1,500. Crown rebuild and flashing repair run $800 to $2,000. A partial rebuild runs $1,500 to $4,000. A full chimney rebuild from the roofline runs $5,000 to $10,000.
How much does a chimney liner cost?
A stainless steel flue liner installed runs $1,500 to $3,500 depending on flue height and diameter. Required when the existing clay liner is cracked or missing. Insulated liners for exterior chimneys cost more.
How often should a chimney be inspected?
The CSIA recommends annual inspection for wood-burning fireplaces, especially before heating season. Gas fireplaces need inspection every 2 to 3 years. Inspection costs $100 to $300 and identifies problems before they become expensive.
Can I use my fireplace with a cracked chimney?
Not safely. A cracked flue liner allows heat and combustion gases to reach combustible framing. Carbon monoxide can enter the living space. Repair the liner before using the fireplace again.
Water coming in around the chimney during rain — repair cost?
Flashing repair runs $300 to $800. Crown rebuild runs $500 to $1,500. If water has rotted roof decking around the chimney, add $500 to $2,000 for decking and shingle repair. Address flashing first — it is the cause in 90% of chimney leaks.
Bricks falling off the chimney with crumbling mortar — repair cost?
Tuckpointing runs $500 to $1,500. Partial rebuild from the roofline runs $1,500 to $4,000. A full chimney rebuild runs $5,000 to $10,000. Falling bricks are a safety hazard to people and roofs below — prioritize immediately.
Chimney inspector said liner is cracked — can I still use the fireplace, and what does repair cost?
A cracked liner is a carbon monoxide and fire risk — do not use the fireplace. Stainless steel liner installation runs $1,500 to $3,500. Full chimney rebuild runs $5,000 to $10,000 if the structure is also compromised.
White staining on chimney bricks (efflorescence) — repair cost?
Efflorescence indicates moisture penetration. Tuckpointing and cap repair runs $500 to $1,500. If moisture has caused spalling (flaking bricks), partial rebuild runs $1,500 to $4,000. Waterproofing sealant ($200 to $500) after repair slows recurrence.
Chimney leaning away from the house — structural repair cost?
A leaning chimney requires immediate evaluation. Partial rebuild runs $1,500 to $4,000. Full rebuild runs $5,000 to $10,000. A chimney leaning more than 1 inch off plumb is a collapse risk — evacuate the area below and call a mason.
Unused chimney with water getting in — should I remove or cap it, and what does it cost?
A chimney cap and crown seal runs $300 to $800 — the cheapest fix for an unused chimney. Full removal to the roofline runs $2,000 to $5,000. Capping preserves the option to restore later. Removal eliminates all maintenance permanently.
